Specification of Letters Patent. Patented A131. 12, 1921.

Application filed April 3, 1920. Serial No. 371,159.

710 all whom it may concern:

Be it known that I, JOHN THoMAs DUCK- won'rH, a citizen of the United States, re-

and concentration of the heating medium with the shell in a predetermined direction-- usually longitudinal of said heater.

The main object of this invention is the provision of a heater ofthe nature referred to which is devoid of coils and which can be cheaply manufactured and readily assembled or attached on any standard type of vertical boiler such as an ordinary household vertical boiler for supplying hot water when desired.

Another object of this invention is to pro- 7 vide a heater of the type referred to which is applicable for prompt attachment on any vertically disposed reservoir, tank or other like receptacle for heating the contents to any requisite degree of temperature.

With the foregoing objects in View my invention consists essentially in certain novel features of construction, combination and arrangement of parts hereinafter fully described and more specifically defined by the appended claims.

In the further disclosure of the invention reference is to be had to the accompanying sheet of explanatory drawings constituting a part of this specification, and in which like characters of reference designate the same or similar parts in all thevie'ws.

Figure 1- is an elevation of a vertical boiler such as is employed for household use and having my invention applied thereto.

Fig. 2 is an inside face View of the heater detached from the boiler.

Fig. 3* is a vertical section of the same; and

Fig. 1 is a horizontal section taken approximately on the line 14= in the precedin figure.

eferring mone particularly to the drawsages with the shell of said boiler ings the numeral 10 designates a vertical household boiler of standard type which is provided with the customary service connections 11 and a supporting foot or base 12, said boiler being ordinarily heated from the stove or range in any of the well known ways, and the present improvements aim to furnish a means- 01? the type described in U. S. Patent No. 1115306; dated October 27th, A. D. 191 1, and of which I became the proprietor and owner by assignment from the inventor-whereby the contents of said boiler 10 may be heated when there is no fire or other source of heat in the stove or range.

According to this invention I make 'a trough-shaped metallic shield 13 which is provided along its longitudinal edges'with spacing members, 1 1 adapted to seat on the boiler 10 and thereby form outlets or pasfor the exit of the products of combustion, and this shield 13 is also closed in at its upper end by a fold over 15 which prevents the flame from emitting beyond the length of the shield as well as serving as a. deflector. The

side walls 16 of the shield 13 are each pierced by a line of small air inlets-or apertures 17 and at the lower ends with larger lighting apertures 18. Attached at appropriate positions on one of the side walls'16 as by nut and bolt connections 19 are thin flexible metallic straps or bands 20 per forated at the free ends with holes 21 for cooperation with the tongue portion 22, of a buckle member 23 conveniently carried by a fold over strap 2&1 attached to the opposed wall 16 by a bolt and nut connection 25 in alinement with the aforesaid connections 19.

Disposed longitudinally of the angular bend of the shield 13 and. extending vertically thereof for approximately half its length is a burner pipe 26 provided at its lower end with an adjustable flexible hose connection 27 and also provided with a plurality of combustion orifices 28 and closed in at its upper end with a closing in thimble 29. In order to properly support the burner pipe 26 in the shield 13 Imake notches or reduced parts 30 at the upper and lower ends thereof in which are disposed bearing bars. or brackets31 conveniently secured to the side walls by bolts and'nuts 32, said bars or brackets serving also to stiffen and prevent the shield from warping due to expansion and contraction.

In practical operation the structure torn ing the subject matter of this application may be assembled with the boiler 10 merely by passing the straps or bands 20 thereabout and buckling them together belt fashion by passing the tongue 22 through the requisite hole 21 in the strap or band 20. Thus it will be clearly seen that practically no'work is involved in the installation of the heater, while the commingled air and gas exuding from the pipe 26 can be easily ignited through one of the apertures 18, furthermore the air holes 17 constitute supplementary air supplies. The products of combustion pass out through the openings constituted by the shell of the boiler 10 and the spacing members 1 1, while the heat generated by the flame is concentrated by the shield and evenly distributed whereby a rapid heating of the water is expeditiously effected.

From the foregoing it will be readily seen that by my improvements 1 provide a cheap, simple and extremely effective heater for the purpose specified; and while I have specifically described its application to a vertical boiler for heating water for household purposes it is to be clearly understood that i do not wish to limit myself thereto as it will be obvious the device is equally applicable for heating vertical reservoirs. tanks and like containers of any liquid or other sub stance necessitating prompt or periodic heating.

Having described my invention What I claim as new and desire to secure by Letters Patent is 1. A heater for vertically disposed vessels comprising a trough shaped shield having its upper end closed in and provided along its edges with projecting lugs serving to space the shield from the vessel to which it is assembled, air and lighting apertures in the walls of the trough shaped shield, strap members attached to one or" the walls or" the shield, buckle members hingedly connected to the opposite wall of the shield, for cooperation with the strapmembers, and a burner pipe supported within the angular portion or trough shaped shield.

2. A heater for vertically disposed vessels comprising a trough shaped shield having its upper end closed in and provided along its edges with projecting lugs serving to space the shield from the vessel to which it is assembled, air and lighting apertures in the walls of the trough shaped shield, strap members attached to one of the walls of the shield and having their free ends perforated with a line oi spaced holes, buckle members hingedly connected to the opposite wall or the shield and having tongues for cooperation with the strap me1nhere, a burner pipe longitudinal of the shield, and supporting bars engaging in notched out parts of the burner pipe for maintaining the burner pipe in position.

In testimony whereof I ai'iix my signature.

JOHN THOMAS DUGKWORTH.
